in
void KstVector::updateScalars()

it is

_scalars["sigma"]->setValue(sumsq = sqrt((_scalars["sumsquared"]->value() - sum * sum / double(_nsum)) / double(_nsum-1)));
_scalars["rms"]->setValue(sqrt(sumsq/double(_nsum)));


it should be
_scalars["rms"]->setValue(sqrt(_scalars["sumsquared"]->value()/double(_nsum)));
